Climate warming can reduce biocontrol efficacy and promote plant invasion due to both genetic and transient metabolomic changes.

ABSTRACT: Climate change may affect plant-herbivore interactions and their associated ecosystem functions. In an experimental evolution approach, we subjected replicated populations of the invasive Ambrosia artemisiifolia to a combination of simulated warming and herbivory by a potential biocontrol beetle. We tracked genomic and metabolomic changes across generations in field populations and assessed plant offspring phenotypes in a common environment. Using an integrated Bayesian model, we show that increased offspring biomass in response to warming arose through changes in the genetic composition of populations. In contrast, increased resistance to herbivory arose through a shift in plant metabolomic profiles without genetic changes, most likely by transgenerational induction of defences. Importantly, while increased resistance was costly at ambient temperatures, warming removed this constraint and favoured both vigorous and better defended plants under biocontrol. Climate warming may thus decrease biocontrol efficiency and promote Ambrosia invasion, with potentially serious economic and health consequences.

Project description:BACKGROUND:In the last five decades a continuous increase in the average global temperature has been recorded. Furthermore, natural disasters (e.g. heat waves, severe storms, floods and large forest fires) are becoming more frequent. The impact of global warming and climate change on health involves an increase in respiratory, cardiovascular, renal and cognitive mental diseases. Furthermore, a change in the frequency and patterns of infectious diseases can also be observed in Europe. MATERIAL AND METHODS:This article presents the most important studies that investigated diseases associated with the climate change, with special reference to those that represent a challenge for intensive care medicine. RESULTS:Currently available epidemiological data and statistical extrapolations indicate that diseases resulting from the climate change (acute infection-related respiratory and intestinal diseases, exacerbation of pre-existing pulmonary lesions, heat-related dehydration, cerebral insults and myocardial infarction) are relevant for intensive care medicine. Particular emphasis is placed on a significant increase in acute kidney damage during heat waves. A previously unknown pattern of infectious diseases necessitates new knowledge and targeted management. In some studies, persisting mental impairments were registered during heat waves and natural disasters, e.g. posttraumatic stress disorder. CONCLUSION:Intensive care medicine must be prepared for the challenges due to global warming and climate change. Slow but continuous changes (e.g. rise in temperature) as well as acute changes (e.g. heat waves and natural disasters) will induce an increased need for intensive medical care services (e.g. an increase in the need for renal replacement procedures). Intensive care physicians will need to be familiar with the diagnostics and management of diseases associated with the climate change. An initiative of the specialist societies involved would be welcomed.
